JOSHUA G. WRIGHT, OF KAHOKA, MISSOURI.

SEED-SOWER.

SPECIFICATION forming part of Letters Patent No. 256,788, dated April 18, 1882.

(N0 model.)

To all whom it may concern:

Be it known that I, JOSHUA O. WRIGHT, a citizen of the United States, resident of Kahoka, in the county of Glarke and State of Missouri, have invented a new and valuable Improvementin Seed-Sowers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of my invention. Fig. 2 is a bottom view. Fig. 3 is a detail top view of the seed-box; Fig. 4, longitudinal section; and Fig. 5 is a detail cross-section.

This invention has relation to seed-sowers; and it consists in the novel construction and arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the annexed drawings, the letter a represents a part of an ordinary cart or other vehicle, supported on axle a and wheels I) b. Attached to this is the seed-box c. The latter may be secured to the rear of a cart-frame, or,in the case of a four-wheeled vehicle, may be attached to the rear or to the front axle, the remainder of the structure being removed, the last arrangement being perhaps the best. The axle a. and the bolster c are recessed at the points a and c and firmly secured to the front of the seed-box c are three tongues, d d d, the reduced ends (1 of which pass between the axle and bolster at the recessed portions. A bolt, 0, passing through the king-bolt hole and a perforation in the tongue d, secures the parts together. These tongues are braced across the top by a board, 0, and rest upon the sway-bar at their outer ends.

The box 0 is formed V shape in cross-section, its side boards, ff, converging, but leaving a space, f, along the bottom, between their lower edges.

Formed on the inside of the ends ggare the guide-grooves g 9 Arranged in the guide grooves g is the slide-board h, having at its ends a suitable gage, and is held adjustably by any suitable means. In the guide-grooves is placed a cut-oft board, 70, which closes the opening inthe bottom when desired. At-

tached to the upper edge of this board is a spring-rod, i, which projects up through a notch, i, in the cover l, and runs through an eye, 1, on a bearing-block, 1

At the front of the cover is secured an open loop, Z into which the end of the rod 2' can be sprung and whereby it is held. This rod is operated as a lever or handle to slide the cut-off board It up or down.

Formed at the ends of the box 0, underneath, are guides at m, in which are placed the side bars, 11 p, of a sieve, the web of which comes under the opening f. This sieve is held under the box by pivotal rods 1), and transverse rigidity is preserved by the braces p Journaled in the ends of the box cis a shaft, q, having angular edges, which is located immediately above the openingf and serves as a stirrer. One end, q, of this shaft projects out of the box, and upon this end is keyed a pulley, g

Secured in any proper manner to the hub of the wheel which is in front of this pulley is another pulley, r, from which there runs to pulley (1 an endless belt, r. Held to the outer face of pulley r by a crank-pin, s, is a connecting-rod, s, which extends to the rear, and resting on a guide-pin, s is connected to a bent lever, t. This lever t is swiveled in the end of rod 8, pivoted to the end of box 0, and passing down over the pin 5' projects through an eye on the end of the sieve. By this 0011- struction as the wheels revolve the shaft q is turned by the belt, and the action of the connecting-rod 8 causes the sieve to reciprocate, the lever t converting the motion.

To better insure the return of the sieve a spring, a, is placed at the end of said sieve farthest from the lever t. Said spring is extended by the pull on the sieve, and operates to draw the latter back to its original position.

Instead of a belt for turning the stirrer-sh aft, a shaft may be used geared properly tothe hub and the shaft q.

Usually strips 2 are placed vertically across the boards h and It, and are designed to prevent seed from accumulating at one point in excess. Riddles of various sizes to suit different grains maybe used.
